Salute
I have some dictionaries, an assorted collection of Oxford, which I can use them on my laptop with no problem, but the problem is that I cannot use them on my KT. A popup says KT isn't able to open the file. I converted some of them through Calibre, mobi to mobi conversion, but an odd problem occurred after conversion: There is no index for dictionary anymore. Moreover I cannot search while using the dictionary, in other words, It's unable to find any word in the book.
I attached a sample of my dictionaries to see if anyone can help me up.

Based on the posts by other K4T K4NT users it seems that these models have some problems with dictionaries in general and are only designed to use the 7 official dictionaries. I.e. they seem to behave like the Kindle apps for PCs and smartphones.
At the moment there's not much you can do other than patching the ASIN number of your dictionaries.
